A method for producing a magnetic transducer including a plurality of heads comprising placing p magnetic cores (such as 17-4), each provided with a winding (scuh as E4) extending over the entire length of the core, on a support plate (20), embedding these cores in an insulating layer (25), eliminating the spirals located at the ends of each core, and connecting the spirals (29, 30) located at the ends of the remaining windings to contact zones (52C, P1, P2, . . . ).

Method for producing a magnetic transducer including a plurality of heads

A method for manufacturing a magnetic transducer including a plurality of heads. This method comprises placing p magnetic cores (such as 17-4) on a support plate (20), each core being provided with a winding (such as E4) extending over the entire length of the core, coating these cores within an insulating film (25), removing the turns located at the ends of each core, and connecting the turns (29, 30) located at the ends of the remaining turns to contact zones (37c, P-1, P-2, etc.). The method applies to the manufacture of transducers with which magnetic printing machines are equipped.
